To all fro/om it may concern.'

Be it known that I, ALEXANDER F RsT, a citizen of the Republic of Hungary, but having declared my'intention to become a citizen of the United States, and a resident of the city of New York, borough of Man# hattan, in the county and State of New York, have invented a new and Improved of which the following is a full, clear, -and exact description.

This invention relates to radiators for automobiles or the'A like and has particular reference to means for obtaining better control of the rcooling of thewater from the engine jacket than is ordinarily possible. v

Among the objects of the invention is to provide a radiator, orwhat is the equivalent of the ordinary radiator, having. the property of bringing the cooling air into direct contact with the water in the formv of a fine spray or mist whereby the greatest cooling effect is accomplished.V y

'Another object of the invention is to propidity o1 circulation of the water so as to controlin the best possible manner the Vdegree or extent of cooling of thewater ac cordingto thevariations of temperature'oi' the weather or likeconditions.l

With the'ioregoing and other objectsin view the invention consists'in the arrangement and combination ofgparts hereinafter described and claimed, and while the invention is notrestricted to the. exact details oi construction disclosed .or suggested herein,

still for the purpose of illustrating a practical embodiment thereof reference is had to the accompanying drawings, in which like reference characters, 'designate the same parts in the several views, and in which- Figure 1 .is aside elevationl of my im.-

provement showing its relation tional typel of engine.

Fig. 2 is a front elevation. ,Fig 3 isa vertical section oit' the radiator on the line 3T3 of Fig. 2; and

Fig. f1 vis a horizontal sectional detail on the 1in@ 4 4 of' Figa. a

to a conven- Referring 'now more specificallyl to the drawings I indicate my invention as applied to an automobile engine 10 supported upon a frame 11 and having secured to and for communication with the cooling jacket a cold water admission pipe 12 and a hot water delivery pipe 13. Said pipe 12 is provided witha check valve 14, and the delivery pipe is fitted with a pump 15 Aof any suitable type for theipurpose of causing a forced circulation of water through the engine/jacket. l

My improvedcooling device for the water which will be referred to herein asthe ra. diator isshown as a whole at 16, but instead of being designed to bel maintained filled K with water as is the usual practice 'it is filled chiefly with airbut it has at the bottom a tray or pan17 supplied with waterto a suivcient depth to insure that the engine jacket and` pipes 12 and 13 shall be kept full of water. The radiator in general design has the appearance of any usual radiator and in. cludes a rim l8having a front flange bounding or determining a large front opening, 19, while the back wall 20 of the radiator is continuous except for a door 21 formed therein normally closed by a vertically lmovable slide 22 movable along guideways 23. Just back of the plane of the front opening 19 are provided a vertical series of horizontal channels 24'constituting bailes. So far as the channels of water baffles 24are lconcerned air may circulate freely and en'- 'tirelylaround the same and along both the c innner and outer` surfaces The ends of the water 'baHes 211 are open and `.tree from the rim portion 18 of the radiator, as shown at 2da. Each baille' as plainly indicated in Fig."

3 has an open frontmouth 25 boundedaboveV and below by flanges or lips 26. Y The lowermost baffle 24f is similar to the others with respect to its' upper portion, but its lower portion extends well down into the pan 17 and is sealed along 'said lower y edge ofthe :front ange portion 'of the rimA 18 so as to constitute'a front wall for the pan and so retain the water well spaced from the opening 19. l .I Each baffle 24, spaced from the next adj acent bathe, coperates with an air baiiie 27 which like the-water baifles 24 is supported at its ends upon the rim of the Vradiator or may be made as an integral part of the rim structure. The front portion of eachfbalile y 27 is projected forward' in an vobtuse angle, the apex 0I" which at 27 is horizontal ,and extends well across the front of the radiator. The rear portions of each member 27 project inward through the mouth portions 25 of two adjacent water baffles 24', the upperk rear portion of each battle 27 projects downward into the lower portion of the surrounding baflle 24, while the other or lower portion of the channel or baille 27 projects upward into the upper portion of the next lower baille 24, but except for the attachment means between the two sets of baffles adjacent to the ends of the baffles 24, all parts of the baflies are `spaced from one another. lt will be seen, therefore, that air will be admitted freely along the slots 28 between adjacent air bailles and such air will flow upward and downward along the inner surface of the water baffles 24 passing thence past the lips 26 into and along the interior of the baies 27 and thence inward through the slots V29 between adjacent baffles 2a into the interior of the radiator. Any suitable openings may be provided'to facilitate the circulation of air inward and through the radiator casing. To this end, the upper portion of the radiator maybe provided with a plurality of apertures 34 of any suitable size which may operate as air vents so as to insure such afdegree of circulation through. the radiator as may be vrequired to secure therdesired end. The radiator cap 30 may also be provided with a vent of the usual type but of a larger size than isusual.

The lower-horizontal portion of the delivery pipe 13 may be termed a nozzle section 31 and may be 'located at any vdesired place with respect to the pan- 17 lying either within the pan or below it. From this nozzle section there extend upward a series of spraying nozzles 32 each of whichis pro- Y vided with an adjustable cock 33'to variably determine the amount Aof opening for the delivery-of hot water upward from the nozzle section 31. rlhe upper end of the spraying nozzle 32 may have any suitable means such as a spiral plug of well known construction for the purpose of deliveringrthe water in a line mist or spray within the air chamber of the radiator. Obviously` the delivery ends of thenozzles extend upward above the level of the water in the pan irrespective of the location of' the nozzle section 3,1. The admission pipe 12 leads from the lower portion of the water jacket into communication with the body of water in the pan 17 The operation may be briefly set forth as follows in view of the foregoing specific description of the construction. Assuming that the water jacket and pipe are filled with water the pan 17 Vis supplied to the desired level and with the slide 22 closed as indicated in Fig. 3 thel device is ready for operation. The pump 15 is adapted ltojbe operated from the motor in any suitable pump willbe causedto operate and cause `the interiorl of the radiator.

the top of the engine jacket, a similar quanf tity of water being drawn upward Jthrough the pipe 12 into the jacket-to take the place of the water pumped therefrom. The water forced downward through the pipe 13 and nozzle 31 will be jetted upward through the spraying nozzles 32 as indicated in Fig. 3 for1ning a cloud of mist or tli'elike within the radiator and in direct contact with cool air admitted thereinto through the slots 28 and 29. The delivery of the water in this manner into the interior of the radiator will tend to the vaporization thereof, but in any event whether the water is ,so delivered in the forni of vapor or as a mist it is cooled rapidly by the air and is deposited into the panl 17 in the form of liquid at a much re duced temperature. There is no loss of waat the front. Any water thatmay find its way into the interior of either set of channels 24 vor 27 will flow freely along the gutters at the bottoms thereof and thence downward along the space 24a at the rim'portions of the radiator. ln cool weather when a less amount of cooling of the water is desired than in summer the cocks 33 may be adjusted sov as to throttle the amount of discharge through the spraying nozzles. Thus the water will be kept warmer in the jacket. The slide 22 is ordinarily kept closed to prevent the loss of water or vapor from the radiator, but may be opened when necessary for the purpose of inspection of As before stated the cap 30 may. constitute an air vent so as to allow a graduated amount of air to be delivered upward through kthe top of the radiator' to facilitate the circulation of air, especially inwarm weather.
